ASTM A36 material is one of the most widely used steel materials in the world. For ASTM A36 material, there are also various names on the market. Such as A36 mild steel, A36 carbon steel, A36 material, ASTM A 36 steel, ASTM A36 steel, etc. No matter how, they mean the same thing. That is, A36 mild steel and A36 carbon steel are the same, just different names among different clients according to their habit.
